T o all 'whom zt may concern.'

Be it known that we, MAHLON E. LAYNEv vision is made for supporting thepacking` for the pum `from theA shaft casing, the said packing takingthe weight of the pump and serving to make a tight joint between thepump casing and the well casing which also serves as the dischargecasing. YThe construction of the present invention differs from that ofsaid applicationin that the packing is'supported by a means independentof the shaft casing, such means preferably being in the form of aseparate pipe surrounding the shaft casing and serving the additionalfunction of a conduit for supply-- ing oil to the bearings in the pump.The supporting means for the packing may also be in the form of an oilApipe (not surrounding the shaft casing) or conduit for other purposes,or in the form of a support from the upper portion of the well which isnot used as a conduit. In its preferred form, as above referred to, thepipe not only funcvtions as a conduit, but gives additional strength andrigidity to the shaft casing, serving to keep such casing straight andpreventing any tendency 'to buckle and thus impose a binding stress uponthe drive shaft which vruns in bearings supported in the shaft casing.The objects and advantages of the construction will more fully appearfrom the following specification and drawings, wherein,

Fig. 1 is a longitudinal section through a well mechanism embodyingrvthe preferred form of the invention, Figs. 2, 3 and 4 are sections onthe lines H II, III-III and IV-IV of Fig. 1; and Fig. 5 is a partiallongitudinal section through a modified structure.

Referring to Fig. 1, the principal parts illustrated may be enumeratedas follows: 1 is the casing of a centrifugal or rotary pump; 2 is a wellcasing` which also acts as a discharge casing and extends to the surfaceof the ground; 3 is the upper end of the inner portion of the pumpcasing, also referred to as the pump neck; 4 is the drive shaft ex#tendingto the surface of the ground and Vop erated'b means of a pulleyor other suitable means (Shot shown); 5 is the shaft casing extendingupwardly from the pump neck to the platfhrm plate 6 located at oradjacent to the surface of the ground, such casing being provided withbearings 5a for the shaft;

and 7 is the lateral outlet from .the upper end of the shaft casing ofthe well casing, from which the discharge ofwater from the pump occurs.

The upper'portion of the pump casing is kturned outwardly 'to form thefiange 8 and beneath this flange is the packing 9 which is designed tomake a tight joint between the pump casing and the well casing 2. Thepacking is supported from beneath by ring 10 provided with a series ofperforations to receive the 'bolts 11, such bolts extending upwardlythrough the l packing and the flange 8 thereabove, and being supportedat their upper ends in the collar 12. The collar 12 is secured toanother collar 13 by means of a series of arms 11i-suitably spaced andconstituting a supporting spider to permit the free passage of waterupwardly through the discharge casing.

The collar 13 lis swivelled upon a sleeve l5 screw-threaded at its upperend to a pipe section 16. A' recess is providedopposite the lower end ofthe pipe section 16 in which suitable packing means 17 are inserted vsothat a tight joint is madebetween the pump neck and/.the lower end ofthe pipe section 16. The pipe section 16 is coupled at its Vupper end toanother section 18 by means of the coupling 19. which coupling isprovided with a plurality of lugs (Fig. 2) 2O extending between theopposite ends of the sections 16 and 18 and engaging the surface of theshaft, casing 5. The shaft casing is preferably machined opposite thevlugs 20 and for a short distance above and below, so that the casingcomposed of the sections 16 and 18 may move up and down andcircumferentially with relative freedom for the purpose hereinafter setforth.

The pipe sections 18 and couplings 19 are duplicated to form a casingextending to the surface of the ground and serving as a support for thecollar 12 and the packing suspended therefrom. The uppermost sectionThissupport 1s accom lished by means of a seriesof bolts 22 having theirlower ends swivelled in the slots 23 provided in the of the angle 28 andupon loosening ilange at the upper end of the pipe section 18. Nuts 24are threaded upon the bolts and held down against the platform 6 bymeansof the annular plate 25 secured in position with the bolts 26. Eachbolt is rovided at its upper end with an integral liead 27 so that bythe application of wrenches to the heads of the bolts, such bolts ma be`screwed up and down, thus raising an lowering the casing made up ofthesections 16 and 18. vThe platform plate 6 is held in position upon thecasing 2 by mealns t is angle the platform' platevmay be given amovement of rotation and this movement of rotation is transmitted to the'upper pipe` section 18 by means of the bolts 22 so that provided with asuitable stuiling box 29 and oil may be su plied to the interior ofthiscasing throug the pipe 30. Similarly the upper end of thepipe section 18is provided with an oil pipe 31, yextending through a suitable gland 32so that the casing 18 may act as a conduit for oil.

The sleeve 15 is provided with an annular recess .33 and asemi-circumferential flange 34as shown in Fig. 4. The lpump neck isrovided with ya corresponding flange 35. his arrangement constitutes ameans for interengaging the sleeve 15 with the pump neck when the sleeve15 -isimoveddown so that the ange 34 lies below the flange 35, .andgthees into vertical alinement. hen the pump is installed in the dischargecasing, the casing made up of the secflan *tions 18 is in its lowermostposition 'with respect to the shaft casing 5 and the pump andY vtheflange 34 lying below the flange 35. The

weight of the pump is thus supported by the pi e sections 18 fand therin 10 lies spaced be ow the packing 9. When te pump reaches the levelat'which it is to be fixed, the platform plate 6 is rotated with respectto the shaft casing 5 thus turning the. casing made up of the sections16 and'18, such rotation being just sufficient to carry the fiangesY 34and 35 out 'of alinement. The bolts 22 are then' screwed lupward throughthe nuts 24, th`us raising the pipe sections 18 and the parts 10,11, 12,13, 14 and 15 carried thereby. This movement is continued until thepacking 9 is compressed and the weight of the pump i'seither partiallyor entirely shifted fromy the-shaft casing 5 to the caslng made up ofthe pi e sections 18, which casing, as hereafter 1n icated, may be usedas an oil conduit and may properly be designated as an oilA conduit.This arrangement provides for a ti ht seal between the pump casing and lthe wel or discharge casing 2, and one which A may be readilydisconnected when it is desired to remove the .pump or re-position it ata different level. n

When it' becomes necessary to release the packin this is accomplished byscrewing down the bolts '22, thus lowering the' oil conduit 18 and thesleeve 15 until the flange 34 lies below the Bange 35. This lowers thepacking supporting ring 10 releasing the packing and shifting the weightof the pump from the oil conduit 18 to the shaft casing 5, The pump maynow be removed by means of proper lifting means applied to the shaftVcaslng or shaft (the platform plate having been released from itsconnection with the dischar casing 2), or in case of injury .to the shaIor shaft casing, the platel 6 may be turned relatively to the shaftcasing thus bringing the flange 34 on the sleeve 15 beneath the iiange35 on the pump neck and Ythe weight of the pump thus transferred to theouter casings 16 and 18 or other similar supports which may or may notconstitute an oil conduit, and the pump then pulled by 'lifting suchcasings. l

The pipe sections 16 and 18 may not only serve as a support for thepacking, but as an oil conduit for carrying oil to the pump. The lowerlsection 16 overlaps the upper end of the oill assage 36 in the pump neckso that oil which is fed downward through the casing enters suchpassageand is supplied to one or more bearings in ,the pump. The manner rinwhich the'passage connects with the bearings may be arranged to suitcondi-` n `.tions and constitutes no part of the present sleeve glven apartial revolution to bring the invention. The oil may be supplied to anoil dome or separator in the pump casing, as shown in the Layneapplication, Serial No, 408,946, and thence fed upward past the bearingsin the shaft casing as described in said application, orA it may besupplied to oil cylinders 37 and thence tothe bearings in the pump asshown in the Layne and Hall application, Serial No. 408,949, or it maybe su plied directly to the bearings.

a heouter casing or oil conduit' also acts as a stifi'ener or bracingmeans for'the shaft casing. Since the weight of the pump and the columnof water in the discharge casing may be either'partially or whollycarried by the oil conduit it is held straight and true, and the shaftcasing, engaged by the lugs 20, is held correspondingly true so that nobindings strains are imposed on the bearings engaging the drive shaft.In some cases the ing ring 39, and extend upward to the surface of theground, having connection with suitable means for raising and lowering.The lower ends of the pipes 38 are connected to the hollow spider 40slidably mounted on the pum neck 47, which spider in turn' cai'- riesthe s ort pipes 41 extending through the packing 42 and are threadedyinto the ring 43 lying below the ring 39 and provided with thecircumferential passage 44 and a downwardly directed opening45. An oilpipe 46 carried by the pump casingand extending to the bearings'of thepump has its upper end extended upward intp the opening 45" and freelyslidable thereinto permit the rings 39 and 43 to be moved lup and downin loosening andtightening tl'ie-. acking.

The pump neck 47 'is connected to t e shaft casing 48 as in the othertype of coiistxguction. In positioning the pump in the well.

casing 49 the weight of the pump is carried by the shaft casing, thepacking and its supporting ring 39 being at such time lowered out ofcontact with the pump casing flange 50. When the pump reaches itsdesired position, the pipes 38 are pulled `upward so 'be desirable.

that the packing is made to engage the ump casing flange lyingthereabove, lan the xweight of the pump 'is transferred from the' shaftcasing to the packing andthe pipes 38 carrying such packing. One ofthepipes 38 may be used for other purposes aside 'from carrying oil suchas indicating-the vacuum.

It is obviousthat considerab e-,modification in the matter of detail maybe' madein the constructions shown and described. The conduits of bothconstructions do not need to be used as oil passages, although this mayindependent of the shaft casing might be used to support the packing.arious constructions may also be substituted for the one of Fig. 1 forraising and lowering the shaft extending upward therefrom, packing fmeans between the well casing and pump casing, a shaft casing extendingupwardly Various other constructions,
